Teleport to PB is just another step towards less pvp, fewer battles, and fewer players. It completely removed screening from the game and the most idiotic thing about it is that that was the intent. From what i understand it was "replaced" with more PvE hostility. Its one of the dumbest ideas to be implemented in this game to date and the people who lobbied for it should re-insert their heads into their asses so we dont get any more great advice. It shuts out national players who arent in the pb from participating in RvR that may directly affect their ability to craft and ultimately play the game. Many many times screening not only created content for more players than were in the actual PBs, but the screening battles were occasionally far more fun than the PBs themselves. On top of all that, the more expensive you make the teleport to limit its use the more you ensure it will only be used by the squads and nations that need it least.
Great decision removing more pvp opportunities on a pvp server in a dying game because of butthurt players who play in stacked nations with no real threats.
